A half-imaginary instrument formed by bending both arms inward at the elbow and placing the right over the left, then using the right arm as a meter needle (much like on a speedometer) to measure the level of "mackage" that one person (usually a guy) is doing towards another (usually a girl, hopefully).

Once the mack-o-meter reaches an approximately 20-25 degrees angle, the mack can be "called" as so desired; anything before it is in direct violation of Man Law.

This noun can be pronounced "Mack-O-Meter" (mak-oh-mete-er) or "mackometer" (mak-om-ett-er); usuage is contextual.
